Volatile organic compounds (VOCs) are harmful to the environment and the human health. The purpose of this proposal is to design and preparation of the new catalysts with high performances at lower temperature, for degrading toluene using the catalytic combustion reaction. A new type of nano-layered MnMxOy (M=Ce, Co, Cu) sample is prepared by a self-propagating method, using as the new carrier. The noble metal Ir, and the bimetallic IrAg active component were loaded to obtain a series of new IrAg/MnMxOy catalysts, for the investigation of their catalytic performances in the toluene catalytic combustion. The effects of nano-particle size on the new catalyst will be investigated, as well as the doping effects on the activity of Ir active sites, and the synergistic effects of bimetallic IrAg in the deep catalytic oxidation of toluene. In addition, the plasma technical enhancement and lamellar material stripping-reassembly method will also be utilized to develop a new layered manganese-based composite oxide-supported noble metal (Ir) catalyst with nanocomposite structure, and their structure-performance analysis will be done for the toluene catalytic combustion. The sample stability will be studied. Combined with a variety of characterization methods, the regulation rule and the structure-activity relationship will be analyzed for the extended new catalysts. This proposed project has theoretical significance and application value for the scientific design and efficient preparation of new high performance catalysts for the toluene catalytic combustion.
